Three Methods Evaluated for Malaria Detection

Malaria is a debilitating disease with high morbidity and mortality in Africa, commonly caused by different species of the genus Plasmodium in humans. Misdiagnosis is a major challenge in endemic areas because of other disease complications and technical expertise of the medical laboratory staff. More...

Device Simplifies Identification of Leishmania Hosts

Researchers have developed a novel device for obtaining essentially painless, minimally invasive microbiopsies (MBs) that mimic sand fly bites and meals, providing a convenient sampling method for identifying asymptomatic, potentially infectious carriers of Leishmania donovani in endemic areas. More...

Standard Test May Miss UTI in Some Women

Urinary tract infection (UTI) is one of the most common infections that people experience. It arises when bacteria, most likely from the skin or rectum, enter the urethra and travel up to the bladder. UTIs affect several parts of the urinary tract, which includes the urethra, bladder, ureters, and kidneys. However, the most common type of UTI is a bladder infection, also known as cystitis. More...
